In diabetic men with erection
problems, the severity of their sexual performance problem
increases as control of blood sugar levels worsens, according
to the results of a new study.
"To our knowledge, this is
the first study of the effect of diabetes mellitus control
on erectile function, describing the severity of erectile
dysfunction in categorical groups, based on a validated
questionnaire," Dr. Ernani L. Rhoden and colleagues, from
the Federal University of Rio Grande do Sul, Porto Alegre,
The findings, which appear
in the medical journal BJU International, are based on a
study of 115 diabetic men who visited a urology center for
erection problems between 2000 and 2001. A blood test that
measures glycosylated hemoglobin (HbA1c) was used to assess
long-term control of blood sugar levels. Erectile function
was evaluated using a standard questionnaire.
The rates of mild, moderate
or severe erectile dysfunction among men with relatively
good HbA1c results were 50, 18, and 32 percent, respectively.
In contrast, among men with poor HbA1c results, a shift
toward more severe dysfunction was seen, with 25, 29, and
46 having mild, moderate or severe dysfunction, respectively.
Further analysis showed that
the association between poor sugar control and the severity
of erectile dysfunction was confined to men who had diabetes
for longer than five years.
"Future studies are needed
to explain the nature of this relationship, and to assess
whether lowering HbA1c serum levels by adequately treating
diabetes mellitus might improve erectile function," the
